Ben Chang	8de3458a07	avcodec/nvenc: surface allocation reduction This patch aims to reduce the number of input/output surfaces NVENC allocates per session. Previous default sets allocated surfaces to 32 (unless there is user specified param or lookahead involved). Having large number of surfaces consumes extra video memory (esp for higher resolution encoding). The patch changes the surfaces calculation for default, B-frames, lookahead scenario respectively. The other change involves surface selection. Previously, if a session allocates x surfaces, only x-1 surfaces are used (due to combination of output delay and lock toggle logic). To prevent unused surfaces, changing surface rotation to using predefined fifo. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>	8 years ago

Timo Rothenpieler	325e56479f	avcodec/nvenc: include nvEncodeAPI v7 SDK header As Nvidia has put the most recent Video Codec SDK behind a double registration wall, of which one needs manual approval of a lenghty application, bundling this header saves everyone trying to use NVENC from that headache. The header is still MIT licensed and thus fine to bundle with ffmpeg. Not bundling this header would get ffmpeg stuck at SDK v6, which is still freely available, holding back future development of the NVENC encoder.	8 years ago

Anton Khirnov	6f58b4dc47	nvenc: drop the hard dependency on CUDA The code needs only a few definitions from cuda.h, so define them directly when CUDA is not enabled. CUDA is still required for accepting HW frames as input. Based on the code by Timo Rothenpieler <timo@rothenpieler.org>.	9 years ago

Anton Khirnov	c59fec783d	nvenc: generate dts properly When there is a non-zero decoding delay due to reordering, the first dts should be lower than the first pts (since the first packet fed to the decoder does not produce any output). Use the same scheme used in mpegvideo_enc (which comes from x264 originally) -- wait for first two timestamps and extrapolate linearly to the past to produce the first dts value.	9 years ago
